Abstract

Pangkep Island consist of 117 Island, situated in Southwest Makasar City, South Sulawesi. These islands  supply  fish and other marine commodity  to the people who lives in nearby town. Unfortunately, they always lack of water, especially at the long dry season.  Usually at rainy season, they collect water from the roof tile  to  storage tank. But at the long dry season the reserve water in not enough to fulfill daily needs. So it is necessary to applied some technology to create fresh water in some island.  One of Island that has chosen as a pilot project is Pandangan Island. Pandangan Island can be achieved from Pangkep City only five hours using tradisional ship. The population around 1200 people and most of them are fisherman. At the long dry season they always lack of fresh water. The reverse osmosis system, capacity 10 m3/day, has been chosen as technology to overcome water problem in Pandangan Island. For remote area, it is assume only 5 liter/day/capita is enough, so the system could fulfill up to 2000 people. The equipment installed in the central Island, using shallow well as a intake water. The efficiency salt reduction is 95 – 98% and recovery ratio 15 – 35%.  The establishment of committee is important to manage operasional of reverse osmosis system. Committee usually consist of 2 technical person and 1 management person, and they come from local people and well train, beside they also should have ability to sell the product water to surrounding island with competitive price.   It’s need big effort to build sea water treatment in each island, so the priority should be determined, especially for crowded, populated and remote island such as Pandangan. Kata Kunci : Air bersih, kelembagaan, pengolahan air laut.

Abstract

Nowadays, the domestic wastewater have become a big problem in Indonesia especially in Jakarta. The governor of DKI Jakarta has established new regulation of domestic wastewater standard which can be discharge to the environment. The regulation namely Pergub 122 tahun 2005. To comply the regullation, PT. United Can Co. Ltd. has already built a domestic wastewater treatment using anaerobic-aerobic biofilter. The wastewater treatment has 130m3/day of treatment capacities. During the start-up periods till 3 months running, the compossition of influent and efluent were analysed weekly. The results show that the concentration of parameter of COD, BOD, TSS, Amonia, pH and MBAS in the effluent have bellow the limit noted in the Pergub 122 th 2005.  Keywords:  Domestic Wastewater, Biofilter, Anaerobic, Aerobic

Abstract

The  increased  use  of  pesticides  has  led  to many  benefits  such  as  advanced  productivity and lower maintenance costs  in agriculture. On the other hand, their  adverse  effects  have  also  grown : an increase of  the risks to the ecosystem and human health. Pressure driven technique such as reverse osmosis and nanofiltration have the potentiality to remove hazardous organic micropollutants such as pesticides. The rejection characteristic of artificial water with 10 ppb concentration of endosulfan and organochlorine pesticides from upper Citarum water shed sample were investigated with a commercial low pressure reverse osmosis unit on laboratory scale. Rejection and flux were measured with a varied operational parameters ; pH, pressure, and feed concentration. Endosulfan rejection was achieved > 80% with all varied operational parameters. There was a little dependence permeate flux and percent of rejection on pH. An increasing pressure caused a higher permeate flux while there was no effect of an increasing pressure to higher percentage of endosulfan rejection. An increasing feed concentration caused a lower permeate flux due to an increasing osmotic pressure.  An increasing feed concentration also result in an increasing percent of endosulfan rejection. Organochlorine pesticides found in river water sample which are lindane, aldrin, and heptachlor were all rejected 100%. This may be caused by natural organic matter present in river water and hydrophobicity. Percent rejection was constant to pressure and pH variation. Keywords : Low Pressure Reverse Osmosis, Organochlorine Pesticides, Pressure, pH, Feed Concentration

Abstract

The treatment process of wastewater contains organic pollutant which used in Indonesia especially in Jakarta is generaly activated sludge process. The problem is its treated water quality which frequently does not yet fulfilled to effluent standard of wastewater. Some affecting factors  are hydraulic retention time (HRT) too short, the fluctuation of wastewater flow rate, unfavorable function of aeration process and also which do not less important is operational mistake caused by insufficient knowledge of operator. To overcome the mentioned problems it is needed technological innovation to increase efficiency of wastewater treatment process especially activated sludge process. Moving Bed Biofilm Reactor (MBBR) technology is one of the  effective alternative for treating wastewater containing organic pollutants. In principle, MBBR is a modification of the activated sludge process is enhanced by adding the media into the aeration tank.This paper describes the study of domestic waste water treatment  using MBBR process which is filled with bioball plastic media which has specific surface 210 m2/m3 as much as 20 % of the volume of the aeration tank for attaching microorganism to increase efficiency and  keep stability of process.Result of the study shows that within 12 hours, 8 hours, 6 hours and 4 hours of hydraulic retention time (HRT) in aeration tank and sludge circulation ratio 0f R = 1.0 Q, the removal efficiency of ammonia were 94.05 %, 93.42 %, 89 %, and 79.6 % respectively. In ammonia loading 0.106 – 0.302 kg/m3.day, the removal efficiency of ammonia were 95.54 – 83.01 %. The greater ammonia loading,  removal efficiency of  ammonia  is getting smaller. Optimal residence time is 6 hours with ammonia removal efficiency reached 89 %, and the average concentration of ammonia in the effluent of 8.3 mg per litre.  Keyword : Domestic wastewater, ammonia, bioball, MBBR.

Abstract

Anaerobic treatment of synthetic wastewater with a high NaCl content was investigated for its effect on the process. The synthetic wastewater, including NaCl up to 40 g/l, was treated anaerobically by draw-and-fill method at a treatment temperature of 37℃ and volumetric loading of rate TOC of 1 g/l/d. TOC removal efficiency and rate of gas evolution rate gradually decreased as salt content increased, although stable operation was maintained. TOC removal efficiency remained high at concentration of NaCl up to 20 g/l, although it fell to 82 % at 30 g NaCl/l. The gas yield at 10, 20 and 30 g NaCl/l were 1.35; 1.10 and 1.00 l/g-TOC loaded, which corresponded to 96; 83 and 78% of that without NaCl, respectively. The content of methane in the evolved gas was 50 to 55% throughout the experiment. Stable operation could not be maintained at 40 g NaCl/l since the TOC removal efficiency gradually decreased with the rapid increased in levels of volatile fatty acidsKata kunci : fermentasi metana, garam NaCl, konduktifitas, asam-asam organik, biogas

Abstract

In County South Bengkulu there are 4 villages classified into poor villages. Those villages do not have some principal facilities yet, such as clean water supply system and electricity. To fulfill clean water need, the people use shallow groundwater which has very bad quality. The groundwater contains Fe (1.7 ppm) and Mn (0.7 ppm). The contents are much more than the standard quality allowed by WHO. The groundwater colour is also a little bit brown. To deal with those problems, BPPT (Agency for the Assessment and Application of Technology) has tried to apply a water treatment system which is supported by a solar cell system producing the electricity. The electric energy is used for pumping the groundwater. The water treatment has a mainly important process which is accommodated in a multy media filter. The media include coarse coral, find coral, sand silica, manganese zeolite and activated carbon. The media filter can reduce the contaminants (Fe & Mn) and remove the odour effectively. The complete water treatment system has been applied successfully in the 4 villages (one for each village).    Keywords : Clean Water Supply Technology.

Abstract

Limbah B3 dapat menimbulkan dampak negative yang sangat besar dan bersifat akumulatif, sehingga kadarnya makin lama akan makin meningkat. Wilayah DKI Jakarta yang padat dengan berbagai kegiatan menghasilkan berbagai jenis limbah yang sebagian bersifat berbahaya dan beracun, yang biasa disebut dengan limbah B3. Banyak pihak yang tidak menyadari bahwa limbah yang dihasilkannya sebagian merupakan limbah B3 sehingga penanganan limbah B3 hanya dipusatkan pada sektor industri dan rumah sakit saja. Hal ini menyebabkan limbah B3 dari sektor domestik  (terutama rumah tangga) terlupakan. Mengingat besarnya resiko yang dapat ditimbulkan dan kondisi yang demikian maka perlu disusun suatu strategi dan prioritas dalam pengelolaan limbah B3 dari semua sumber yang ada. Keywords: Hazardous waste.
